DEVIGE FOR SECURING BRAKE-HEADS TO BRAKE-BEAMS.

QPECZEICATION forming part of Letters Patent No. 442,138, dated December 9, 1890.

Application filed September 5, 1890. Serial No. 364,035. (No modehl To all whom it may concern:

Be it known that I, HENRY B. ROBISCHUNG, a citizen of the United States. residing at Kalamazoo, in the county of Kalamazoo and State of lliichigan, have invented certain new and useful Improvements in Devices for Securing Brake-Heads to Brake-Beams; and I hereby declare the following to be a full, clear, and exactv description of the same, reference being had to the accompanying drawings, in which-- Figure l is a plan view of a trussed metallic brake-beam, portions broken away, a supplemental attaching-block embodying my invention, and a brake-head and shoe, the attaching-block, brake-head, and shoe being in horizontal section. Fig. 2 is a side view of the supplemental attaching block, brakehead, and shoe. Fig. 3 is a detached view of the brake-head. Fig. & is a rear or back view of the brake-head. Fig. 5 is an end view of an attaching-block embodying my invention, and Fig. 6 is a rear View of said attachingblock. Fig. '7 is a modification in which a broken loop or two undercut lugs are used.

Like symbols refer to like parts wherever they occur.

My invention relates to the construction of supplemental attaching-blocks, whereby the usual or common forms of brake-heads may be readily and securely attached to brakebeams of forms not originally intended for use with said heads. The common form of brake-beam heretofore in most general use has been a wooden beam of substantially rectangular cross-section, and the approved form of brake-heads have consequently been generally formed with a rectangular recess or seat for the reception of the end of the brakebeam and with a back plate or laterally-projecting rear flanges (see Figs. and I) for attaching the head to the beam. Owing to the different means employed for securing the shoe to the head, and for other reasons, said brake-heads have sometimes a single central bolt-hole and sometimes two laterally-placed bolt-holes, as shown in the drawings, for bolting the head to the beam.

The devices of the present invention, while of general utility for the purpose specified,

have been devised more especially for that class of the common form of brake-heads wherein two laterally-placed bolts are pro vided for.

The invention, generally stated, consists in asupplementalattaching-block having afaceplate or table provided at one end with a loop, or overhanging lateral lugs the equivalent of the loop, adapted to receive one flange of the back plate of a brake-head and with a throughbolt or equivalent device at the other end for binding said back plate to the face-plate or table of the attaching-block, substantially as will hereinafter more fully appear.

I will 110w proceed to describe my invention more fully, so that others skilled in the art to which it appertains may apply the same.

In the drawings, A indicates the beam, B the post or strut, and C the tension-rod or truss-rod, of any approved form of metallic beam, the particular construction being immaterial, as the same forms no part of the present invention.

1 indicates the supplemental attachingblock, preferably of cup or box form, as shown, though any form which will embrace the end of the metallic beam may be adopted.

The means for securing the supplemental attaching-block to the beam forms no part of the present invention, and may be, if desired, the ends of truss-rod C with nut c and recess and lug (Z, as indicated on the drawings, or any other suitable means to meet any particular character of metal beam.

Formed with or attached to the supplemental attaching-box, in aplane which will stand parallel or substantially parallel with the axis of the beam A, is a table or face-plate 2, provided on its sides at. or near one end with undercut lugs 3 3, (see Fig. 7,) which may, if desired, be extended or joined to form a loop 3*, (see Fig. 5,) which is the preferred form, as giving the greatest strength and security for the parts. These undercut lugs or the loop formed therefrom are intended to receive one end of the back plate or laterallyprojecting flanges a (I. (see Fig. a) of the common brake-head.

Near the end of table or faceplate 2, opposite to loop 3 and usually in the central line,

' of the metallic brake-beam.

is a bolt-hole 4 for the reception of a bolt 5 or its equivalent,which, coacting with loop 3 or lugs 3 3, binds the back plate a a of the brake-head firmly upon the table or faceplate 2.

Then in use, the supplemental attachingblock 1 is-first properly secured to the end One end of back plate a a of the brake-head is then inserted under the undercut lugs 3 3 (or their equivalent, the loop 3) and moved endwise until the'bolt-hole near the opposite end of the back plate a registers with the bolt-hole 4, after which the bolt 5 is inserted and the nut thereof tightened to bind the parts secur'ely together.

In addition to the advantages of simplicity, durability, and facility with which thebrakehead can be removed and replaced (the bolt 5 being to the outside) Without disturbing the brake-beam the undercut lugs or l0opconstruction herein described enables the back plate to be shifted endwise, so that any common form of brake-head having two laterally-placed bolt-holes can be applied without drilling bolt-holes at special points in the faceplate or table of the attaching-block.

undercut lugs and at its opposite end with a clamp adapted to bind the back plate of a brake-head to the said faceplate of the attachingbiock, substantially as and for the purposes specified.

2. A supplemental attaching block for brake-beams, said block having a faceplate provided on its sides, at or near one end,witl1 undercut lugs which unite over the plate to form a strap or loop, and having at the opposite end a bolt-hole for the reception of a clamp-bolt, substantially as and for the purposes specified.

In testimony whereof I affix my signature, in presence of two Witnesses, this 30th day of August, 1890.

HENRY B. ROBISCHUNG.
